File: patch/u-boot/v2025.04/cmd-fileenv-read-string-from-file-into-env.patch:76-86
Timestamp: 2025-03-31T22:20:48.475Z
Learning: For the Armbian build project, maintaining consistency with existing patches across U-Boot versions (such as between 2025.01 and 2025.04) is prioritized over refactoring individual patches for code improvements.

File: config/boards/lckfb-taishanpi.csc:5-9
Timestamp: 2025-07-25T03:51:50.830Z
Learning: When reviewing PRs in the Armbian build system, U-Boot defconfig files and patches may be added as part of the PR changes but might not be visible in the current repository clone state during review. It's important to check the actual PR file changes directly via GitHub or the PR API to get the complete picture of what files are being added or modified.

Timestamp: 2025-09-14T06:32:29.806Z
Learning: In the Armbian build system, the write_uboot_platform() function implementations follow different patterns across Rockchip family files. The newer standard (used in rockchip64_common.inc and rk3506) includes 'status=none' parameter in dd commands, while older implementations (rk3288, rk322x) use an older pattern without this parameter. The rk3506 implementation correctly follows the current Rockchip family standard.

File: config/sources/families/uefi-x86.conf:0-0
Timestamp: 2025-11-06T15:36:04.682Z
Learning: As of PR #8879, the uefi-x86 family in the Armbian build system now includes kernel patches for the first time. The current and edge branches for uefi-x86 are specifically configured for Apple T2-based x86 machines, including T2-specific patches from the linux-t2 project and custom kernel configuration options for Apple hardware drivers.

Timestamp: 2025-03-31T22:20:41.849Z
Learning: When porting patches between U-Boot versions (like from 2025.01 to 2025.04), rpardini prefers to maintain patches as-is rather than introducing refactoring changes, even when potential improvements are identified. This approach prioritizes consistency and reduces the risk of introducing new issues.

Learning: In the Armbian build system, rk3576 boards consistently use BOARDFAMILY="rk35xx" for both vendor and edge kernel targets. The rk35xx family configuration sources rockchip64_common.inc, which provides edge and current kernel branch definitions, making these branches available even though they're not defined directly in rk35xx.conf.

Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.

Learning: In Armbian's Rockchip vendor kernel branches (rk35xx-vendor), device tree files may not require the same headers as mainline Linux. For example, input key definitions like KEY_BACK and KEY_VOLUMEUP may be handled differently in BSP kernels and don't necessarily need explicit includes like <dt-bindings/input/input.h> that would be required in mainline kernel device trees.

Timestamp: 2025-07-17T04:12:33.125Z
Learning: In the Armbian build system, board configuration files (*.conf) follow a project standard of not including shebang lines, even though they contain bash code and are sourced by the build system. This is an established Armbian convention that individual contributors are expected to follow, and changes to this standard would require broader project maintainer approval.

Timestamp: 2025-09-18T03:36:17.862Z
Learning: In Armbian board configuration files (regardless of file extension), the standard pattern is to have only one line as a comment describing the board hardware specifications. This single-line description typically includes the SoC model, core count, RAM options, and key features like connectivity options, storage interfaces, and special features. The file extensions indicate board support status: .conf (standard support), .csc (community supported), .eos (end of support), .tvb (tvbox), .wip (work in progress).

Learning: In the Armbian build system, BOOTBRANCH_BOARD is a valid framework variable used as a fallback when BOOTBRANCH is unset. The framework checks BOOTBRANCH_BOARD before applying the default bootloader branch value (see config/sources/common.conf). Board configuration files can use BOOTBRANCH_BOARD to specify the bootloader branch.

Timestamp: 2025-09-14T06:29:18.958Z
Learning: In the Armbian build system, vendor branch configurations in family files are designed to be shared across multiple SoCs within the same family that use the same vendor kernel tree. For example, rk35xx and rockchip-rk3588 families both use identical vendor branch settings (same KERNELSOURCE, KERNELBRANCH, and KERNELPATCHDIR), demonstrating that vendor branches are intentionally generic rather than SoC-specific.

Timestamp: 2025-11-10T22:05:40.490Z
Learning: In the Armbian build system, kernel branches using non-mainline/vendor forks (like BeagleBoard's linux repository) should be named "vendor" or "vendor-rt" rather than "current" or "edge". The "current" and "edge" naming is reserved for mainline kernel branches. This affects both the case statement in family config files (e.g., `vendor | vendor-rt)` instead of `current | current-rt)`) and the corresponding KERNEL_TARGET declarations in board config files.

Timestamp: 2025-08-02T05:46:10.664Z
Learning: In the Armbian build system, the modern recommended approach for kernel configuration is to use the kernel-config command via "./compile.sh BOARD=boardname BRANCH=branchname kernel-config" instead of the deprecated KERNEL_CONFIGURE=yes flag. This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.

Learning: In config/bootscripts/boot-mvebu.cmd, the `fdtfile` variable is mandatory for booting and is pre-set by U-Boot, but can be overridden via armbianEnv.txt. If `fdtfile` is empty, the subsequent device tree file search logic will eventually fail and trigger the critical error "Cannot find DT!" with proper error handling.

36-38: LGTM! Mainline ATF integration looks correct.The BOOT_SCENARIO change to "tpl-blob-atf-mainline" and re-calling prepare_boot_configuration() is the correct approach to leverage ATF code from rockchip64_common.
59-64: LGTM! Documentation function serves its purpose.This function correctly documents that upstream U-Boot for rock-5b already includes UMS support, eliminating the need for typical patching that might be required for other boards.
66-76: LGTM! Boot order modification is correctly implemented.The boot order change (SD → NVMe → eMMC → USB → PXE) aligns with the PR objectives and is correctly implemented using sed to modify the rockchip-common.h header file.

The newer standard (used in rockchip64_common.inc and rk3506) includes 'status=none' parameter in dd commands, while older implementations (rk3288, rk322x) use an older pattern without this parameter. The rk3506 implementation correctly follows the current Rockchip family standard.Learnt from: igorpecovnik Repo: armbian/build PR: 8849 File: config/boards/radxa-e54c.csc:14-28 Timestamp: 2025-11-02T20:49:56.719Z Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.Learnt from: djurny Repo: armbian/build PR: 8287 File: config/bootscripts/boot-sunxi.cmd:38-44 Timestamp: 2025-06-12T21:14:36.024Z Learning: In config/bootscripts/boot-sunxi.cmd the unconditional "+1" increment in func_align_addr_next (when align_overlap_oboe_avoidance="on") is intentional. It compensates for a known off-by-one error in U-Boot where the end address is calculated as start+size instead of start+size-1, so the extra page prevents overlap. This behavior should not be “optimized away”.Learnt from: EvilOlaf Repo: armbian/build PR: 8428 File: config/boards/lckfb-taishanpi.csc:5-9 Timestamp: 2025-07-25T03:51:50.830Z Learning: When reviewing PRs in the Armbian build system, U-Boot defconfig files and patches may be added as part of the PR changes but might not be visible in the current repository clone state during review. It's important to check the actual PR file changes directly via GitHub or the PR API to get the complete picture of what files are being added or modified.Learnt from: glneo Repo: armbian/build PR: 8913 File: config/sources/families/include/k3_common.inc:57-60 Timestamp: 2025-11-11T20:56:20.303Z Learning: In config/sources/families/include/k3_common.inc, the OP-TEE build command at line 59 should be updated in a future PR to explicitly set CROSS_COMPILE64=aarch64-linux-gnu- and CROSS_COMPILE32=arm-linux-gnueabihf- instead of relying on OP-TEE's internal defaults, for better clarity and maintainability. User glneo agreed to address this in a separate PR.Learnt from: tabrisnet Repo: armbian/build PR: 8661 File: lib/functions/compilation/armbian-kernel.sh:194-201 Timestamp: 2025-09-22T21:52:01.225Z Learning: In lib/functions/compilation/armbian-kernel.sh, the kernel_config_modifying_hashes array is not universally required for all kernel configuration functions - some functions like armbian_kernel_config__netkit() operate without it, and adding entries with '=m' would be incorrect when the actual result might be '=y' for options already built-in.Learnt from: tabrisnet Repo: armbian/build PR: 8661 File: lib/functions/compilation/armbian-kernel.sh:194-201 Timestamp: 2025-09-22T21:52:01.225Z Learning: In lib/functions/compilation/armbian-kernel.sh, the kernel_config_modifying_hashes array is not universally required for all kernel configuration functions - some functions like armbian_kernel_config__netkit() operate without it, and adding entries with '=m' would be incorrect when the actual result might be '=y' for options already built-in.Learnt from: EvilOlaf Repo: armbian/build PR: 8754 File: config/boards/bestv-r3300-l.csc:14-16 Timestamp: 2025-10-14T05:08:11.785Z Learning: In the Armbian build system, BOOTBRANCH_BOARD is a valid framework variable used as a fallback when BOOTBRANCH is unset. The framework checks BOOTBRANCH_BOARD before applying the default bootloader branch value (see config/sources/common.conf). Board configuration files can use BOOTBRANCH_BOARD to specify the bootloader branch.Learnt from: EvilOlaf Repo: armbian/build PR: 0 File: :0-0 Timestamp: 2025-08-02T05:46:10.664Z Learning: In the Armbian build system, the modern recommended approach for kernel configuration is to use the kernel-config command via "./compile.sh BOARD=boardname BRANCH=branchname kernel-config" instead of the deprecated KERNEL_CONFIGURE=yes flag. This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.
42-46: No action required — the patch directory can be intentionally absent.Per the Armbian build system's established handling of patch directories, patch directories referenced in BOOTPATCHDIR configurations can be non-existent without causing build failures, and missing patch directories should not be flagged as errors during code review. Since this PR is only updating the board configuration for v2026.01-rc2 (a release candidate with no Armbian-specific patches yet), the absent
patch/u-boot/v2026.01/directory is intentional and acceptable. The directory can be created in a future PR when Armbian patches become necessary for this U-Boot version.Likely an incorrect or invalid review comment.
